Application filed. December 29, 1913. Serial No. 809,387.

I To all whom it may concern:

Be it known that I, VITALIANO TOMMA- SINI, a subject of the King ofItaly, residing at 42-44 Via Ponte Seveso, Milan, in the Kingdom ofItaly, have invented certain 'new and useful Improvements in Apparatusfor the Manufacture of Stuffed Alimentary Iastes, tion. I

The invention has for its object a machine for the manufacture ofstuffed alimentary pastes *and more particularly, ravioli, comets and soforth.

A machine constructed in accordance with the present invention isillustrated by way of example, in the accompanying drawing in whichFigure 1 shows a piece of paste from which a ravioli is made.

Fig. 2 is an elevation and Fig. .3 a plan of the finished product.

Figs. hand 5 are elevations of opposite sides of the machine.

Fig. 6 is a plan.

Figs. 7 and 8 show two different positions of the device by which thestuffing is fed to the sheet of paste.

Figs. 9, 10, 11 and 12 are detail views of the cutting, foldingiandindenting mecha'nism.

Figs. 13, 14 and 15 are details hereinafter more particularly referredto.

The machine comprises:

1. A feeding device for the 2. A device for feeding thestuffing-material onto the sheet of paste.

- ments ofthe cutting apparatus.

3. A device which cuts and forms the peripheral indentations upon thepiece of paste (Fig. 1) which isafterward folded back upon itselfto-form the ravioli.

f. A device which folds back the said piece of paste (Fi 1) insueh amanner as to inclosethe stu ng material this device pressing the edgesin such manner as to produce, the final product represented in Figs. 2and 3.

The device for effecting the operation of feeding the paste presents noappreciable difference as" compared with other devices employed in othermachines for the manufacture of alimentary pastes.

Referring to thedrawings, the sheet of paste 1 (Figs. 4 and 5) receivesan intermittent feed movement, the intervals of stoppage being suitablycoordinated to the moveof which the following is a specificawill beunderstood that in operation the tation, toward 'piston 21 is displacedin the channel 20 so .26 mounted upon sheet of paste.-

The feeding movement is effected by means of'the shaft 2 which carriesthe driving pulley 3, and apair of gear wheels 4. and 13-130 the shaft6, which latter controls the shaft 7 carrying the pawl 8, by means ofcranks 9 and 10 and a connecting rod 11. Through the intermediary of thetoothed wheel 12 the pawl 8 produces the advance of the sheet of paste 1step by step by means of the roller 14 which is itself operated by theratchet wheel 12 driven by the pulleys 15, 16 and 17'which areconnecttogether by a chain transmission. It

roller 14: is actuated by means of chains which receive an intermittentmotion from integral with the ratchet thus accomplishesstep-bydisplacement corresponding the pulley 15, Wheel 12 which step anangular to the advance. bined action of rod 11 and pawl 8. The stuffingcontained in the hopper receptacle 18 (Fig. 7) is displaced by the screw19 which is given a movement of continuous fo the channel 20. The small'75 of a tooth due to 'the COIIh' as to cause the stuiiing to advance.After passing through the member 22 intended for cutting and indenting,and the perforated table 23 (Fig. 4) fixed to the frame, the stuiiingbecomes deposited upon the severed piece of paste 24 (Figs. 8 and 9). Acam the shaft 6 (Fig. 5) is adapted to'impar't a vertical reciprocatingmovement to the hopper and the parts connected therewith during whichmovement the hopper is guided in the grooves 25 (Fig. (i) in the frameof the machine. This vertical movement is rendered necessary owing totheconnection of the. hopper with the member serving to cut and indent thepaste.

The screw 19 is'rotatedthrough worm gearmg 27, 27, driven in turn'bythree gear wheels 28, 29,30. The latter are mounted upon a shaft 31driven by a shaft 6 by means of a chain 13. As the gear wheels 28, 29,30 must follow the changes in position of the Worm gearing 27, 27, wheel30 is mounted upon arms 32, 33. To enable the small pist0n-21 toexpelthestufiing from the hopper casing 18, .it

receives a more rapid movement of descent than that of the hopper 18,the desired speed of the member 18. tained by expulsion resulting fromthe member 21 relatively to the pivoting the plate 34:, fixed to Thisrelative movement is obbeing struclnfrom the end ofasmall post a lprojecting upward from the receptacle; Z2 1 i is the center of a pivotaround which the bell.

teiulant releases the pawl y when the counthej small piston 21, throughthe intermediary of the small connecting rod 35,

to the leverj36pivoted at 38 upon an arm fixedto theyl'iopper casing"18. The knob 37 at the extremity of the lever 36 while participatinginthe reciprocating movement of the.hoppelytraverses the slot 39 andtransmits to the lever 36,36 an oscillating movemeet, the profile of theslot 39 being such ofthe piston 21 relatively to the hopper that thisoscillationgives rise to a movement p casing lS diu-ing the downwardmovement of the latter. i 1

W hen thestufling is moist and hasa tendelncy to stick to the wallsofthe hopper rece'ptacle 18.; an'anxiliary device shown at Fig. of tliedrawings isresorted tom order to secure a perfectly regular feeding. The"hopper receptacle 18 is in thiscase of circular shape, the center I) ofthe circle crankshaped lever 0 can freely rotate.

The lever c is prbvided at its outer end". '1 with a pistonrlicorresponding 1n 'shapeto theicross section of the hopper receptacle1'8.

' To the lever cissecured a rod 0 carrying 'at its outerend acounter\\-'eight. A pawl jg pivoted; at hill on said lever 0 engages anabutment'z'of the'post a and keeps the lever ingthe position shown infull lines in the figure; \Vhenit is desired to'cause the.

piston (Z td enter the ho rper receptacle 18 in order to push the stu ngdown, the 'attemveight will cause thewhole device to take the positionshown in dotted lines :and the: piston (.Z to follow the descendingmotion of ,the stufiing.

As shownin Fig. 6 apluralityof propeller-"screws are *alined along the"width of the casing with their respective worm driving gears 27, 27(four being shown in the traverseil' by the small pistonQl, providedwith a lower flange .4-0, having an arched cutting periphery 141 which fs preferably, indented as shown (luigralniuatically in Figs.

mad 9, 'so as to sever and form the indentedperiphery on the;cir,cularipi ece of paste (Fig.1) and thereafter turn it back.

I y'lhe piece of paste 2+ to which the piston 21. hassupplied'theqstufling and which the severing auclinilenting member hascomnienced tdturn over, is seized by the cylinders 43, 43 which closeit, completely by uniting theedges-nas indicatedin Figs. 10 and 11. Thecylinders 43 are provided with i ravioli for the purpose of closing thelatter,

thisclosing being effected by the compression of the edges of thepieceof paste. It is necessary that the cylinders 43, should notcommence to carry the ravioli with them before the latter-has receivedthe stuiiing and. it is also necessary that the stuffing should be fedto the ravioli while it is still. stationary. To this end the twocylinders 43 are driven from the shaft 6 through the chain transmissions46 and 17 to the shaft "l8 (Fig. 13) from which the movementistransmitted to the pinion 4:9.monnted upon due of the cylinders 43through the intermediary "of two wheels 50 51 (Fig. 13) which arepartially toothed, and a wheel 51.

v The plainand toothed portions of the wheels 50, 51 are of suchdimensions that when the feed of the sheet of paste ceases, thecylinders 43 for effecting the folding and closing operations alsostop,inasmuch as when, during its rotation, the last tooth of the toothedportion of wheel 50 leaves the lasttooth of the toothed portion of wheel51 and the plain portions of the wheels 50, 51

are adjacent to one another, the wheels 51,, 51 will cease rotating,until the first advancingftooth of the rotating wheel 50 meshes againwith the toothed portion of wheel 51. During this interval the cuttingof the piece of paste and the deposit of the stuffing thereon takesplace.

The cylinder 43 operated by the pinion 49 transmits movement to theother cylinder by means of a pair of pinions 52, 52

(Fig. 14). The rotating cylinders 43, 43 are hollow and internally theyare traversed by fixed rods 531 '(Fig. 12) carrying brushes 55 (Figs. 9and 10) which serve to clean the interior of the cylinder by expellingtherefrom any stuffing thatkmay have I penetrated the aperture 44,45.The ravioli, when finished, fall from between the'cylin-' ders 43 ontothe endless apron (Fig. 4)

1 which discharges them from the machine.
